Hello,
Hope you are doing well!
When I place a call from iPhone to iPhone, there is a problem with voice, my own voice echoes in speaker of same device, no voice got listened on another device. In case of call from iPhone to Android or Android to iPhone voice work seamlessly.
I noticed the issue after updating the OS versions of my iPhone to iOS 11.0.2. May be issue is related to OS but I am unable to figure out the exact issue. Please help me to short out the issue asap.
Waiting for your response. Thanks in advance!
Thanks & Regards,
Vivek Shukla
